Kennametal 6370972 Replaceable Drill Tip 0.7874 in 140 Deg

Product Description

The KENNAMETAL 6370972 is a replaceable drill tip designed for use with KTFST-series modular drilling systems. Built from fine-grain solid carbide and finished with a PVD-applied AlTiN coating, this tip delivers thermal and wear resistance in demanding cut conditions. It measures 0.7874 inches (20.00 mm) in cutting diameter with a 140-degree drill point angle and an HPL insert geometry. The tip uses a clamp-style holding method and seats in an insert seat size Y holder. Internal coolant-through channels direct cutting fluid directly to the cutting edge. Licensed machinists and CNC operators working in job shops or production environments are the typical installers.

This drill tip is suited for drilling operations in stainless steel and similar M-grade workpiece materials. The helical, regular-spiral flute design with two flutes and two margins supports chip evacuation in through-hole and blind-hole applications. The KTFST series geometry also accommodates inclined exit drilling and stacked-plate drilling setups where a stable, controlled cutting action is required. A functional length of 0.3937 inches and a flute length of 10.00 mm make this tip appropriate for shallow-to-moderate depth drilling passes in a modular tooling setup.

Key Features

• Fine-grain solid carbide substrate in manufacturer grade KCMS15 for toughness and edge retention
• PVD-applied AlTiN coating resists heat and built-up edge in stainless steel applications
• 140-degree point angle with HPL insert geometry reduces thrust force at entry
• Two-flute, two-margin helical design supports chip control and hole finish
• Coolant-through construction delivers fluid directly to the cutting zone
• Clamp-style insert holding in seat size Y for repeatable indexing in KTFST-series holders

Compatibility

Designed for use with KTFST-series modular drill bodies accepting insert seat size Y and ISO number KTFST20000HPLM. Intended for primary use in stainless steel (workpiece material code M) drilling applications.

Installation Notes

Installation is performed by machinists or tooling technicians. Always power down and lock out the machine spindle before seating or removing the drill tip. Use the appropriate torque tool specified by the holder manufacturer for the clamping screw - do not overtighten or use an impact driver. Inspect the insert seat for chips or debris before seating the tip to ensure proper contact and runout performance.
